* llvmpipe: implement scissor testingBrian Paul2010-01-141-2/+17
| | | | | | | | | | | The scissor test is implemented as another per-quad operation in the JIT code. The four scissor box params are passed via the lp_jit_context. In the JIT code we compare the quad's x/y coords against the clip bounds and create a new in/out mask that's AND'd with the main quad mask. Note: we should also do scissor testing in the triangle setup code to improve efficiency. That's not done yet.
* llvmpipe: initial mrt supportKeith Whitwell2010-01-101-1/+1
| | | | | Non-mrt apps work, and the code looks correct, but not many mrt test apps handy atm...
* Merge remote branch 'origin/master' into lp-binningJosé Fonseca2010-01-081-10/+3

* | llvmpipe: do final the pixel in/out triangle test in the fragment shaderBrian Paul2009-12-161-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test to determine which of the pixels in a 2x2 quad is now done in the fragment shader rather than in the calling C code. This is a little faster but there's a few more things to do. Note that the step[] array elements are in a different order now. Rather than being in row-major order for the 4x4 grid, they're in "quad-major" order. The setup of the step arrays is a little more complicated now. So is the course/intermediate tile test code, but some lookup tables help with that. Next steps: - early-cull 2x2 quads which are totally outside the triangle. - skip the in/out test for fully contained quads - make the in/out comparison code tighter/faster.

* llvmpipe: Code generate the texture sampling inside the shader.José Fonseca2009-09-071-0/+27
| | | | | | | | | | Finally a substantial performance improvement: framerates of apps using texturing tripled, and furthermore, enabling/disabling texturing only affects around 15% of the framerate, which means the bottleneck is now somewhere else. Generated texture sampling code is not complete though -- we always sample from the base level -- so final figures will be different.
